Abstract:
A data caching technique is provided that is highly scalable while being synchronous with an underlying persistent data source, such as a database management system. Consistent with the present invention, data is partitioned along appropriate lines, such as by account, so that a data cache stores mostly unique information and receives only the invalidation messages necessary to maintain that data cache.
